Given numbers are 491,206,428

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 491,206,428 is 21645244.

Find LCM of 491,206,428 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 491 x 103 x 214 = 21645244

Therefore, the lowest common multiple of 491,206,428 is 21645244.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

491 x 206 x 428 = 43290488

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

491 : 1, 491

206 : 1, 2, 103, 206

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 491,206,428, is 1.

Now, the common factors can be found like this.

491:491

206:2x 103

428:2x 2x 107

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 43290488/(1x2)

LCM = 43290488/2

LCM = 21645244

Thus, we can understand that the LCM of 491,206,428 is 21645244.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 971, 661, 346
• LCM of 522, 706, 146
